Best FM's Interactive Poster Gets People to Shake Their Heads

This interactive poster ad from Best FM, a radio station, encourages people to bop their heads either side to side or up and down in order to reveal a surprise.

The ads make use of perspective illusions, so that when you tilt or shift the position of your head, the silhouettes of iconic musicians like Elvis, Freddie Mercury and Michael Jackson come to life and seem to appear out of nowhere. This is done by using multiple layers for the print, a cutout and a back-lit component. The colorful ads are similar in style to those iconic Apple iPod ads and even though there might not be any music playing around these ads, they cleverly reiterate Best FM's tagline, which states that the radio station plays "Music that makes you move."
